Specification forming part of Letters Patent No. 200,249, dated February 12, 1878; applicationfiled July 28, 1877. I

To all whom it may concern:

Be it known that we, BYRON O. BRADLEY tached thereto. Fig.4. represents a sleeve used on the axles. Fig. 5 is a detail.

This invention relates to devices for regulating the depth of the plowing and for lifting the plow out of the ground; also-to a removable sleeve, by the use of which the pitch and gather of the wheels may be adjusted and the sleeve renewed when worn.

That portion of our invention which relates to the regulating and lifting devices is debracket 0. 'N is the seat, which is supported signed to be used with plows in which the plow-beam is pivotedor hinged to a crankaxle; and it consists in a lever attached directly to the axle, and arranged to engage with a rack or some othersuitablc device con nected with the plow-beam, so that when the I plow is in use and the lever engaged with such rack orother device the plow cannot turn upon the crank, nor the crank turn in the socket connected with the beam, while the crank is free to turn in its bearings, while at thesame time the plow can be lifted out of th ground by the use of this same lever.

In the drawings, A A represent the wheels. B isra crank, one end of which is provided with a spindle, a, to receive the wheel A. The other end, I), of this crank ends at the point 0, the other wheel, A, being located upon an independent spindle, rigidly secured to an arm, F, which arm is pivoted at its forward end in a socket in another arm, E, which is hinged upon the crank B. O O are two brackets, hinged upon the crank B. D is a cross-bar, permanently Secured to the upper H is a plow-beam. It is hinged to the outer or swinging portion of the crank B in such manner that it cannot move thereon longitudinally. This can conveniently be done by means of a long socket or hub, j, permanently secured to the under- J is a rack, attached at its ends to the plowbeam." Kis a casting, having at the lower end two flanges,at right angles to each other,

which are fitted and secured in the angle of the crank in both portions thereof. The upper end of this casting has a socket. L- is 'a lever, permanently secured in the socket in K. Practically K L together form the lever.

S is a spring, the lower end of which is secured in the socket in K, and the upper end of which rests against the lever. The lever has a projection on the inside to engage with the notches in J, and the spring holds the lever against the rack. A spring-lever, L, might be used, and the spring S dispensed with.

M is the tongue, which is secured to the upon a bar attached to the cross-bar D; The lower end of this bar extends some ways below D, and upon the lower end thereof is a short cross-bar, which serves as a stop, 0, for the front end of the plow-beam.

dis a'hook or latch, pivoted to the inner end of the bracket 0. e is a pin or catch upon the inside of K, with which the latch 01 engageswhentheplowisabovethe ground; This latch can be lifted by the foot of the driver pressing upon the forward end, or the extension f thereof. a is a foot-rest for the driver.

It will be observed that the lever L has no connection with the tongue, directly or indirectly, but that it is practically permamently secured at its lower end to the crank B, so that when engaged with the rack J the tongue is loose and free to move up and down. At the same time the plow will be held rigidly upon the crank by means of the lever and rack, and the plow-beam cannot turn in the crank, neither can the crank turn in the socket upon the beam, but the crank can turn in the bearings at its ends.

By means of the lever, which can be made to engage with the rack at different points, the depth of the plowing can be adjusted.

When the lever is disengaged from the rack by lifting thereon, the crank can be lifted, turning in its. bearings, thus raising. the plow entirely out'of the ground, and it can be there held by means of the latch cl engaging with the pin 0. In doing this the front end of the beam will first be raised until it comes in contact with the stop 0 then, as the crank'cone tin ues to rise, the front of the beam will be depressed, and the heel of the plow raised.

the plow-beam is free to move upon the crankaxle, so that, as it is raised or lowered to adjust the depth of plowing, these parts adjust them selves to each other.

Instead of the rack shown, the lever might be made to engage with and operate a clutch placed upon the crank, andarranged to engage withnotches in the socket, or with some device attached thereto, which will accomplishfrom hard to soft'soil, the depth of the. cutting will be the same, since the. weight of the machine-and driver must be ra-isedin order to raise the plow even partially out of the ground.

justing the pitch and gather of the wheels, which consists in a removable sleeve, the hole through which forthe axle is not parallel with the axis ofthe sleeve, .but'is. somewhat diagonal thereto, as shown in Fig. 4:, in which 9 is the spindle, h the sleeve. As shown, the hole for the spindle is not concentric with the end of the. sleeve at either end. It might be which the inside ofthe hub of the wheel comes in contact, so that'the sleeve: cannot'rotate on the spindle, but the wheel rotates on the sleeve.

The recess which receives the projection '11 may be located on the top, or on either side of the part in which it ispl'aced,\and its position, i, remaining unchanged on the sleeve, determines the pitch and gather of the wheels. When the lever is disengaged from the rack The sleeve can be replaced when worn, and the axles or spindles remain unworn.

Our improvements may be used with a machine having a continuous crank-axle, adapted to receive a wheel on each end. As we have described the machine, one wheel is upon one end of the crank, the other is upon an independent spindle, which construction has been adopted in connection with certain devices for leveling the plow. transversely.

What we claim as,ncw,anddesire to secure by Letters Patent, is

1. Ina snlky or gang plow, a plow hinged" upon a crank,.in combination with a lever permanently secured to the crank, anda rack or other equivalent device connected with'the plow-beam,for the purpose of raising and lowering the plow independently of the as specified.

2'. A plow-beam hinged to-a. crank, B",'in"

combination with the frame 0 Disupporting a seat, tongue M,stop 0,.lever L, and rackJ, substantially as and for the purpose set forth. In Fig. 4 we have shown a device for ad y 3. The sleeve h, providedwith spur/i, to fit a corresponding recess in the spindle-arm, and

having thehole that receives the spindle diagonal to or not concentricwith the circumference of the sleeve, whereby the-sleeveis prevented from turning upon the spindle, and

the'pitch' or gather of the wheel'is regulated, substantially as specified.
